Find the potential of the point in the origin in regard to referring point at infinity if there's charged line laying on x-axis as shown in the picture.

## Homework Equations

## The Attempt at a Solution

I know two ways to find a potential:

V=∫dV and V=∫

**E*dl**

using first formula i have dv=dQ/4πε

_{0}r and i have Q=Q'dl but i don't know how to integrate that, i mean i have dl and i don't know what to do next.
